Well, I had really been waiting for auto road-joining to become available, but finally got bored enough to just say screw it and try my hand at some scenery building. I chose a really tiny area for my practice run, a place called Thitu island, but I find some sort of very noticable bug in ocean rendering in that area, with large rectangular areas of the sea simply being invisible.
Something to possibly take a look at, for the devs.
